Definitions

  • the invention relates to a circuit for feeding a air intake manifold of a vehicle engine automobile in compressed air supplied by a turbocharger.
  • circuits for supply of compressed air intake manifolds from a turbocharger There are many examples of circuits for supply of compressed air intake manifolds from a turbocharger.
  • the feed of the collector is carried out independently by the first branch and the second branch which each have a valve associated independent service intended to feed the in air directly from the turbocharger or cooled air having circulated through an air / air exchanger better known as intercooler name.
  • Each of these valves is conventionally controlled by an associated independent pneumatic actuator, the actuators being synchronized inversely with respect to the other.
  • the air that is admitted into the intake manifold may not be allowed at the desired temperature, which may disrupt the operation of the engine.
  • the two valves are grouped into one unique case that forms a mixer and has two butterflies parallel each forming a valve and having an axis common which is rotated by a pneumatic actuator unique.
  • the invention proposes a mixer of the type previously described having two independent axle throttles controlled by an actuator unique.
  • the invention proposes a circuit of the type described previously characterized in that the mixer comprises a first and second secant axis ducts, intended to be each connected to the first or second associated branch and throwing in a third duct intended to be connected to the collector of admission, and in that the first and second conduits each have at their junction with the third conduit progressive sealing means, the sealing means progressive first and second conduits being synchronized conversely from each other and actuated by means of common control.
  • FIG. 1 shows a circuit 10 for feeding of an air intake manifold of a combustion engine motor vehicle, represented schematically by the reference 16, compressed air supplied by a turbocharger schematically represented by the reference 18.
  • the circuit 10 comprises a branch input or conduit 12 which is connected to the output of a collector of turbocharger 18 and an output branch or conduit 14 which is connected to the inlet of the intake manifold 16 of the engine.
  • the circuit 10 also comprises a first branch 20, interposed between the turbocharger 18 and the collector 16, in which the air circulates through an air / air exchanger 22, for ensure the cooling of the air circulating in the said first branch 20, and a second branch 24, interposed between the turbocharger 18 and the collector 16, in which the air circulates directly at its outlet temperature of the turbocharger 18.
  • first known conception of the state of the technical circuit 10 comprises a first housing 26, interposed upstream of the second branch 24, which comprises a flap internal (not shown) that is likely to close progressively the second branch 24 to spread the air circulation between the two branches 20 and 24.
  • the circuit also comprises a second housing 28, interposed downstream of the first branch 20, which is likely to close progressively the first branch 20 to spread the air circulation between the two branches 20 and 24.
  • Both housings 26 and 28 are synchronized inversely from one another in opening and closing, so that a flap of a housing 26, 28 is open when the other housing is closed, and vice versa.
  • This design poses a problem of congestion of a on the one hand, and on the other by the synchronization of the two enclosures by two independent control means proves to be problematic, both from the point of view of reliability than of obtaining a effective synchronization.
  • the air supplied to the intake manifold 16 may not be not be adjusted to the required temperature, thus penalizing the engine operation.
  • the two housings 26 and 28 can close the circuit, thus depriving the intake manifold 16 of air and interrupting the engine operation.
  • This mixer 30 comprises a body 34 comprising the essential one main conduit 36 which is intended to be connected to the manifold 16 intake.
  • This main conduit is pierced with two openings 38 and 40 parallel within which are mounted around the same axis 42 two butterflies 44 and 46 angularly offset by 90 ° with respect to each other.
  • Each openings 38 or 40 is connected to a branch 20 or 24 associated circuit 10 as shown previously, so that the air flow from the branch 20 is synchronized inversely, the flow of air coming from the branch 24, which makes it possible to mix the air from the first and second branches 20, 24 in proportions determined to confer a temperature determined by the air admitted into the collector 16 intake.
  • Both butterflies are actuated by an actuator single tire 48, a rod 50 causes the axis 42 by through a lifter 52.
  • This design allows for reliable synchronization of butterflies 44 and 46, but is very cumbersome.
  • the invention proposes a mixer 30 of the type of that shown in FIG.
  • the mixer 30 comprises a first conduit 54 and a second conduit 56 associated "A" and "B" axis lines, intended to be each connected to the first or second branch 20, 24 associated and throwing into a third conduit 58 intended to be connected to the manifold 16 intake.
  • the first leads 54 and the second leads 56 each comprise at their junction with the third conduit 58 associated means 60, 62 of progressive shutter, the means gradually closing the first and second ducts 54, 56 being synchronized inversely with one another and actuated by a common control means 64.
  • each means 60, 62 of progressive closure of each first / second conduit comprises a butterfly 66, 68 of a diameter equal to that of the conduit 54, 56 associated and mounted to rotation about an axis 70, 72 diametral of said duct 54, 56.
  • the axes 70, 72 of the butterflies 66, 68 of the first and second conduits 54, 56 pass through the first and second conduits 54, 56 and are each coupled to a rudder 74, 76 associated, the pedals of the two ducts being connected by a connecting rod 78 common to maintain a constant position angular relative of the butterflies 66, 68 according to which a butterfly is closed 66, 68 when the throttle 68, 66 opposite is open, for synchronize the butterflies 66, 68 inversely one of the other.
  • control means 64 Any control means 64 known to the state of the technique may be suitable for actuating the butterflies 66, 68.
  • the common control means 64 consists of a means of pneumatic control actuating the connecting rod 78 common.
  • control means 64 tire comprises a housing 80 inside which a membrane 82 delimits two chambers 84 and 86 of pressure opposites, of which at least one is likely to be subject to variable pressure to actuate the membrane 82 which is secured to one end 88 of a rod 90 whose other end 92, protruding outside the housing 80, is coupled to the connecting rod 78.
  • This design effectively ensure synchronization and controlling the butterflies 66, 68.
  • one of the first or second leads 54, 56 for example here the second duct 56 is coaxial with the third duct 58 and the other, here the first duct 54 is perpendicular to the third duct 58.
  • the butterflies 66, 68 are resiliently biased to a position in which the butterfly 66 of the first conduit 54 associated with the first branch is open and in which the butterfly 68 of the second conduit 56 is closed.
  • This configuration ensures that in case of failure of the pneumatic control means 64, the third led 58 feeds the air intake manifold 16 having crossed the air / air exchanger, since in case of impossibility regulating the temperature of the intake air, it is better to supply the engine with cooled air rather than air hot directly from the collector of the turbocharger 18.
  • the butterfly 68 is for example recalled to its closing position by a spiral spring (not shown) and the connection of the butterflies 66, 68 by the connecting rod 78 ensures automatically returning the butterfly 66 to its position opening.
  • This configuration is obviously not exhaustive of the invention, and one could envisage a configuration according to which the butterfly 66 is resiliently biased towards its position opening, or a configuration in which both butterflies 66, 68 resiliently biased, the butterfly 66 being recalled to its open position and the butterfly 68 being recalled to its closing position, or a configuration according to which the connecting rod 78 is resiliently biased into a position opening of the butterfly 66.
  • the invention therefore makes it possible to regulate in a simple and effective the temperature of the air admitted into a collector intake of a turbocharged engine.
